Geochemistry and Biogeochemistry

Our research program studies the earth surface including chemical weathering, soil formation, and biogeochemical cycling. We focus on soil processes, also known as the Critical Zone: that area of the earth's surface where lithosphere, hydrosphere, biosphere, and atmosphere intersect. We use isotopic and trace element geochemistry to understand how these processes impact landscape evolution, global elemental cycles, and ecosystem productivity. ​

November 2015:Elizabeth King on the radio! Listen here to Liz talk about her research using molybdenum isotopes as a paleoredox tracer.

October 2015: Elizabeth King spent the month at the University of Georgia running redox fluctuation experiments on soils she collected from the Luquillo Critical Zone in Puerto Rico as part of the CZO Summer Intern Fellowship she was awarded this past year.

Winter 2015: Elizabeth King was chosen as an NSF representative for the WUN Summer School at the University of Western Australia looking at the effects of climate change on soils. Check out the video of her experience here!
